Simple flow for pushing another view controller on modal dismiss

ModalViewController.swift

protocol ModalViewControllerDelegate {
    func pushToAnotherScreen()
}

class ModalViewController: UIViewController {
    
    // MARK: - Properties
  weak var delegate: ModalViewControllerDelegate
  
  lazy var cancelButton: UIButton = {
    let button = UIButton()
    button.title = "Cancel"
    return button
  }()
  
  // MARK: - View Life Cycle
    
    override func viewDidLoad() {
        super.viewDidLoad()
      button.addTarget(self, action: #selector(handleCancel), for: .touchUpInside)
    }   
  @objc func handleCancel() {
    dismiss(animated: true) {
            self.delegate.pushToAnotherScreen()
        }
  }
}

PresentingViewController.swift

class PresentingViewController: UIViewController, ModalViewControllerDelegate {
    
    // MARK: - Properties
  
  lazy var button: UIButton = {
    let button = UIButton()
    button.title = "Show Modal"
    return button
  }()
  
  // MARK: - View Life Cycle
    
    override func viewDidLoad() {
        super.viewDidLoad()
        button.addTarget(self, action: #selector(handleShowModal), for: .touchUpInside)
    }
  
  @objc func handleShowModal() {
    let modalViewController = ModalViewController
    modalViewController.delegate = self
    self.present(modalViewController, animated: true, completion: nil)
  }
  
  // MARK: - Modal View Controller Delegate.
  
  func pushToAnotherScreen() {
    // implementation to push to another screen
    let newViewController = UIViewController()
    self.navigationController?.pushViewController(newViewController, animated: true)
  }
  
  
}
